You teach five classes, manage thirty-plus students, and carry a semester's worth of curriculum in your head. Claude can help with almost everything — drafting feedback, differentiating materials, planning lessons — but it has a hard stop: the moment you close the conversation, it forgets all of it.
Next session, you're back to square one. Who is Marcus? What level is your Year 9 set? What did you cover last Friday? Claude doesn't know. You're re-briefing from scratch.
This post explains how to fix that. The short version: add one URL to Claude's settings and Claude gets a persistent memory you build over time — student notes, lesson plans, curriculum threads, all queryable in plain English whenever you need them.
A few patterns that come up consistently:
These are the things you carry in your head. Stash gives them a home Claude can actually reach.
No re-briefing. No "who's Marcus again?" Claude knows because you told it, and Stash remembered.
Once your standing context is set up, every morning session can begin with one word:
context()
You write this once into your standing context collection:
I'm a secondary school English teacher. I teach Year 9 (mixed ability), Year 10 (set 2), and Year 12 (A-level). This term's focus: Year 9 narrative writing, Year 10 persuasive writing, Year 12 unseen texts. My prep day is Wednesday. I like when Claude formats differentiated materials in a table.
Every subsequent conversation, Claude loads this in under 200 tokens. You spend zero time re-orienting it.
| What you store | Approximate records |
|---|---|
| 30 student profiles | 30 records |
| 10 lesson plans (versioned) | 10–20 records |
| Assessment notes per term | 30–60 records |
| Resource lists (3 units) | 15–30 records |
| Total (one class, one term) | ~90–140 records |
The free tier gives you 2,500 records and 50 queries/month. For a single-class teacher, that's a full year's worth of notes with plenty of headroom. Manage multiple classes and you'll likely want the Pro tier (25,000 records, 500 queries) at £8/month.

After sign-in, create a "Year 10" collection and start adding student notes. Claude will be able to query it in any future session.
The feedback we hear most: it's not that Claude becomes smarter — it's that you stop losing the work you've already done to brief it. Student context, lesson planning history, assessment observations — these represent real effort. Stash makes that effort compound rather than evaporate at tab close.
